PHOTOGRAPHIC PROJEGTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 623,410, dated April 18, 1899.

Application filed February 12,1898. Serial No. 670,134. \No model.)

To all whom, it may concern:

lie it known that we, WILLIAM VELLETTE MILLER, of Bayonne, in the county of Hudson, and GEORGE PEEcIvAL RICE, of Rutherford, in the county of Bergen, State of New Jersey, have invented a new and Improved Photographic Projecting-Machine, of which the following is a full, clear, and exact descript-ion.

IO The invention relates to vitascopes,'liinematographs, kinetoscopes, biographs, and similar machines; audits object is to provide a new and improved photographic projecting-machine arranged to impart a positive I5 intermittent traveling motion to a film Without danger of vibration of the film while at rest, so as to insure the production of a perfect picture, the film being positively fed equal distances without the slightest variation to insure a complete and full registration of every picture With the field of the lens.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference inclicate corresponding parts in all the figures.

Figure 1 is a plan view of theimprovement.

Fig. 2 is a sectional front elevation of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged transverse section of part of the improvement on the line 3 3 of Fig. 4. Fig. 4 is an enlarged sectional front elevation of the same on theline A l of Fig. 3. Fig. 5is atransverse section of the same on the line 5 5 of Fig. 4. Fig. (3 is a similar enlarged view of another part of'the improvement on the line 6 6 of Fig. 1, and Fig. 7 is a longitudinal section of the oscillating and sliding shaft and adjacent parts.

The film A, madein the form of a continuous sheet, is provided on its sides with the 5 usual equidistant apertures A, adapted to be engaged by the feed mechanism, as hereinafter more fully described, for imparting an intermittent traveling motion to the film through a slide 13, having an opening B in the field of the lens for permitting the projecting of a picture on a screen or for making exposures in the usual manner. lhe slide B is preferably disposed vertically for the film to travel in a similar direction through the slide, andthe latter is attached to a tube B fitted to slide in a casing B secured tothe bracket G of the main frame 0, on which the machineis mounted. A rnck-and pinion movement 13 serves to impart a sliding motion to the tube B in itstubularcasing B for conveniently introducing the film into the slide at the time the slide is out of range with the feed mechanism for the film.

The feed mechanism consists principally of two wheels D D, placed a suitable disfeed-wheels D D leave a clear space between their opposite faces for the uninterrupted passage of the light to and through the slideopening 13, the wheel D being secured to a shaft E, turning at one end in a bearing 0 the main body of said shaft being mounted to turn in a hollow shaft F, while the other wheel D is secured on a shaft E, mounted to turn in a bearing C carried by the frame C. The two shafts E E are in alinement with each other, but extend in opposite directions from their wheels, so as to leave a clear space between the opposite faces of the wheels for the purpose mentioned.

The hollow shaft F is mounted to turn and to slide longitudinally in suitable bearings O G carriedby the frame 0, and on the end of said hollowshaft, adjacent to the Wheel D, is secured an L-shaped arm G, having its horizontal member G overhanging the peripheral surfaces of the wheels D D. On the under 5 side of said member G are formed or secured radially-extending teeth G2 G adapted to engage registering notches D Dflrespectively,

formed in the peripheral surfaces of the wheels D D, respectively, as will be readily understood by reference to Figs. 3 and 4.

As shown in Fig. 3, the wheels D D are provided with eight such registering notches D D"; but itis evident that a larger or smaller number of notches may be employed, according to the length of the pictures on the film, it being understood that the arm G engages with its teeth G G a pair of registering notches and then swings and turns the wheels oneeighth of a revolution at a time to feed the film in the slide 13 a corresponding distance that is, the height of a picture-so as to bring successive pictures into the opening B.

In order to impart a rocking motion to the hollow shaft F and the arm G carried thereby, said hollow shaft is provided with a downwardly-extending arm H, carrying a frictionroller H, in engagement with a cam-groove I, formed in the periphery of the cam I, secured to a cam-shaft J, journaled in suitable bearings 0, held on the frame C. The groove 1" in the cam I is so arranged that for every full revolution of the said cam a full forward-andbackward stroke is given to the arm G. The cam-shaft J is provided with a gear-wheel J, in mesh with a gear-wheel K, held on ashaft K, journaled in bearings C on the frame 0, and the outer end of said shaft is provided with a grooved pulley K orother means @011- nected with other machinery for impartinga continuous rotary motion to said shaft K, the motion of which is transmitted by the gearwheels K J to the cam-shaft J. A sliding motion is given to the hollow shaft F from the cam-shal'tJ at the time the arm II is ata standstill and the friction-roller 11 thereof travels through the straight portion of the cam-groove 1. For this purpose the hollow shaft F is provided with a collar Ii, formed in its periphery with an elongated groove L, engaged byafriction-roller N carried on the upwardly-extending member of a three-armed lever N, having its horizontal member formed with a forkN straddling a four-faced cam P, secured on the cam-shaft J. The three-armed leverN is fulcrumed loosely on a shutter-shaft 0, carrying the usual shutter 0, having its opening. 0" in alinement with the opening 13 during the period of rest of the film A, said shaft 0 and its shutter 0 being driven from the cam-shaft J in unison with the feed mechanism for the film. The shaft O is for this purpose provided with a gear-wheel O in mesh with an intermediate gear-wheel O in mesh with a gear-wheel O, secured on the camshaft J.

The downwardly-extending memberof the three-armed lever N is connected by a link Qv with a bolt R, forming a locking device for the wheels D D during the period of rest, said bolt having a do\vnwardly-extending arm R, pivoted at R to the frame 0 of the machine. The belt R is provided at its ends with teeth It" R", adapted to engage a pair of registering notches D D in the wheels D D at the time the said notches are in a lowermost position.

By reference to Fig. 2 it will be seen that the threearmed lever receives a swinging motion from the cam P on the cam-shaft J, so that a sliding motion is given to the hollow shaft F and its arm G in one direction, while the link Q, imparts a rocking motion in the opposite direction to the bolt R. Thus by this arrangement the bolt R and the arm G simultaneously receive motion for moving the teeth G G of the arm G in mesh with a pair of notches D D at the top of the wheels D D at the time the teeth R R move out of engagement witha corresponding pair of registering notches at the bottoms of the wheels D D, and a reverse movement takes place when the arm II swings in an opposite direction, so that the teeth G G move out of mesh with their notches at the time the teeth R It move in mesh with the notches at the bottoms of the wheels. As this movement of the teeth of the arm G and that of the locking-bolt R takes place at the same time, it is evident that the wheels D D are positively locked againstrotation during the period of rest, principally, however, by the bolt R, assisted by the arm G, prior to the beginning of the oscillating movement of the arm and at the end of the said movement.

It is understood that when the machine is in motion the cam I by its connection with the hollow shaft F imparts a rocking motion to the latter and to the arm G, and the other cam P by its connection withsaid hollow shaft F causes the same to slide in a longitudinal direction in such a manner that the oscillating and sliding movements alternate. Thus when the several parts are in the position shown in Figs. 1 and 2 the wheels I) D are at a standstill near the end of the period of rest, and when the shaft J rotates in the direction of the arrow a (see Fig. 2) then the cam P acts on the three-armed lever N and shifts the shaft F and the arm G in the direction of the arrow 1) to move the teeth G G out of engagement with the notches D" D at the top of the wheels D D, (see Fig. 4-,) and at the same time shifts the bolt R from right to left in the inverse direction of the arrow Z) to move the teeth R lt in engagement with the pair of registering notches D 01 D at the bottom of the wheels D D. This takes place during one-fourth of a revolution of the shaft J, and during which time the friction-roller II travels in a straight portion of the camgroove 1', so that the hollow shaft F is not rocked in its bearing. During the next onefourth revolution the lever N remains at a standstill, while the cam I imparts a swinging motion to the arm II to swing the arm G in the direction of the arrow 0 (see Fig. S3 to bring the teeth G G in alinement with the next pair of registering notches D D. D uring the next onequarter revolution the frietion-roller II travels in the straight part of the cam-groove I, so that the rocking of the shaft F ceases; but during this quarter-revolution the cam I again acts on the lever H and swingsthe same in an opposite direction to shift the hollow shaft F in the inverse direction of the arrow Z), so as to move the teeth G G in mesh or engagement with the registering notches, as indicated in dotted lines in Fig. At the same time the bolt R is shifted from the left to the right to move its teeth out of engagement with the notches D D at the bottom of the wheels D D. During the next quarter-revolution of the shaft J a swingin g motion in the inverse direction of the arrow 0 is given by the cam I to the shaft F and its arm G, so that the wheels D D are now given one-eighth of a turn to feed the film A downwardin the slide B and bring the next picture into register with the slide-opening 13'. The above-described operation is then repeated that is, upon a further turning of the shaft J the bolt R is moved into position for locking the wheels D D, while the arm G moves with its teeth out of mesh with said wheels, then swings to the position shown in dotted lines in Fig. 3, then moves in mesh with the wheels, while the bolt moves out of mesh with the same, and then the arm is rocked back to its former position to again turn the wheels D D for again feeding the film, as described.

Now it is evident that by the improvement specified a positive feeding of the film takes place without danger of vibration of the film while at rest, as the feed mechanism is positivel y locked in position during the period of rest by the locking-bolt R and partly by the teeth of the arm G, as previously mentioned. Furthermore, the film is positively fed equal distances without the slightest vibration, thereby insuring a full registration of every picture with the lens.

The mechanism described permits of running the machine at a very high rate of speed with absolute registration of the pictures with the field of exposure.

It is especially noted that the feed mechanism engages the film at the sides of the slide-opening, so that the film is not loose at the said opening, but is locked at this very point by the feed mechanism during the period of .rest and is bodily moved at this point by the samemeans during the period of feeding. As the feed mechanism is rigidly locked with the film, the latter cannot possibly vibrate and mar the effect.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1.
